Study in a second language without switching apps. Read PDFs with aligned translation, follow bilingual lecture captions and ask AI in context. Try Pro free for 14 days.
BBnotes is an AI notebook for international students studying in a second language. Translate PDFs side by side, follow lectures with bilingual captions, handwrite with Apple Pencil and ask an AI tutor about the exact passage, formula or note on the page—all in one study workspace.
READ AND TRANSLATE PDFs
• View the original text and its translation side by side.
• Scroll both versions together to keep the same passage aligned.
• Keep the source visible while you highlight, annotate and handwrite.
FOLLOW LECTURES IN TWO LANGUAGES
• Record a lecture and see bilingual captions on supported devices.
• Review a timestamped bilingual transcript after class.
• Jump back to the relevant moment instead of searching the entire recording.
ASK AI IN CONTEXT
• Circle a passage, formula or handwriting and ask directly from the page.
• Keep each question and explanation connected to the source material.
• Get guided explanations and next-step prompts when working through a problem.
WRITE, ORGANISE AND REVIEW
• Take handwritten notes with Apple Pencil on iPad.
• Generate an outline to navigate long documents.
• Keep important explanations beside the material they refer to.
• Bring reading, writing, translation, lecture audio and AI support into one notebook.
BUILT AROUND THE STUDY DAY
Use BBnotes before class to prepare, during class to follow along, and after class to return to what was said and where it appeared in your notes.
Download BBnotes for free. New users get a 14-day Pro trial. Optional Pro plans and AI point packs are available as in-app purchases. Pricing is determined by your local App Store.
Available on iPhone, iPad and Mac. Some features require compatible devices and system versions, and feature availability may vary by platform.

What's New in BBNotes 1.75
A transcript panel you can move anywhere: On iPad and Mac, drag the transcript bar up or to the side and it becomes a floating panel you can put anywhere on screen. Drop it near the bottom and it docks again. While it's floating, drag the bottom corners to resize it, down to 220pt wide. On narrow panels, less-used buttons move into a "⋯" menu.
Custom translation colours for live captions: Choose blue, black/white, orange, red, green or purple, so translations stay readable on blue slides. The palette button sits next to "Aa" on the caption bar.
Read back through the transcript without being pulled down: Scroll up and new lines won't interrupt you. A "↓ N new" button appears so you can jump back to the latest line.
Recall for text boxes and sticky notes: In Recall mode, tap a text box or sticky note to jump to the point in the recording where you added it.
Improvements & Fixes
Live transcription during recording is on by default again, so captions no longer seem to disappear after updating. If you turned it off yourself, it stays off. The Transcription & Translation settings now have a "Close" button that is always visible, and Esc closes them too.
File and folder names can include "?" and other punctuation instead of having them replaced with "_".
Two notes with the same name, created in the same folder on different devices, used to block each other's sync. Now one is renamed to a conflict copy and both are kept.
PDF export keeps highlights and annotations from your slides. Text, images and text boxes appear in the right place on rotated pages, AI screenshots include text boxes, page thumbnails show text boxes, and lasso selection is more accurate.
Closing a window directly on Mac or iPad now stops the recording and saves it properly.
One damaged item in a note no longer wipes out everything else of that type. The damaged data is kept in a separate file so it can be recovered.
Imported notes with an uppercase .BBNOTE extension now open and sync normally.
If a move or rename can't be completed, it's undone and you're told, so the next sync won't move the note back.
Switching accounts no longer reuses the previous account's sign-in token.
Memory use during long recordings with live captions is more stable.
Dragging the transcript panel on Mac no longer expands or collapses it by mistake.
